WEATHER-STRIP.

Specification of Letters Patent.

raaenieanov. so, rain Application filed January 27, 1917. Serial No. 144,885.

To all whom it may concern:

Be it known that I, RALPH W. CRoss, a citizen of theUnited States, and a resident of Dallas, in the county of Dallas and State of Texas, have invented a new and Improved Weather-Strip, of which the following is a full, clear, and exact description.

My invention relates to the type of weather strips comprising mating members applied respectively, to the door or window frame, and to the door or window, the one member presenting a groove and the other member a tongue to enter the grove.

In certain weather strips of the type referred to a channel bar and other expedients are employed, designed to trap the water, or otherwise prevent the water entering beneath the sash or door, but wind or draft forces the water between the tongue and groove members comprising the weather strip, causing annoyance and not infrequently damage.

.The' prime object of my invention is to provide a weather strip of the type referred to, which is rain proof. draft proof, durable, compact, and easily applied, and one that will not result in the sash or door sticking or binding but which will be self-adjusting under conditions due to shrinking 0r.swelling of wood structures, or following the I settling of the house or like contingencies.

The distinguishing features of my invention and the advantages will appear as the description proceeds.

Reference is to be had to the accompanying drawings forming a part of this specification in which similar reference characters indicate corresponding parts in all the views.

Figure 1 is a transverse vertical section of a Weatherstrip showing my invention embodied inrthe groove member of a casement window at the bottom to co-act with a known form of channel bar presenting a tongue, the View showing the window partly open;

Fig. 2 isa View similar to Fig. 1 but showing the window closed;

Fig. 3 is a horizontal section on the line 3-8,l?ig. 1, showing the application of the invention to the window and frame at a side thereof;

Fig. 4 is a fragmentary view in horizontal section in the same plane as Fig. 3, showing on a larger scale, the parts indicated at the upper portion of Fig. 3;

Fig. 5 is a transverse "ertical section showing the upper and lower sashes of a sliding window, equipped with a. form of my invention at the meeting rails of the sashes, at the bottom and sides of the lower sash, and at the top and sides of the upper s F g. 6 1s a fragmentary view in vertical section on an enlarged scale of the devices shown at the upper right hand corner of Fig. 5. I Referring more particularly to Figs. 1 to 4L which show the'invention applied to a. casement window at the bottom and at a side thereof, the letter A indicates the sill; B, the window frame; C, the sash; c a groove in the bottom rail of the sash; and c a vertical groove in the side' stile of the sash.

The numeral 10 indicates a known form of channel bar which is suitably secured to the sill A as by screws 11, said bar presenting a vertical splash member 12 at the outside, a loiver inner wall 13 terminating at its upperfend in an approximately horizon tal tongue 14, the splash member 12 having drain holes 15 therein. i Ordinarily, in practice the rigid tongue 14 is received in a groove in the sash presenting rigid walls so that even a slight shrinkage of-the sash or frame or a slight settling of the building will throw these rigid members out of line, thereby not infrequently preventing the sash closing tight, thus making the conditions worse than would be the case if no rigid tongue and mating groove were employed. in winds and storms, water trapped in the channel bar 10 is forced over the inner wall 13 of the channelbar by wind entering the ,holes 15. To overcome the objections referred to, I provide self-adjusting elements so arranged as to. insure an effective contact between the channel bar 10 or equivalent devices presenting a tongue, and the surfaces engaged by these in the mating groove. Thus, in thebottom rail of the sash C I provide at the groove 0 an element 16 identified generally as the groove member, the bar 10 and its element 14: being generally re ferred to as the tongue member of the strip. The element 16 is formed of resilient sheet metal and presents a vertical drip member 17 at the front. At the upper end of the drip member 17 the material of the element 16 is returned on itself at the inside and extends from the top of the grooved obliquely Moreover, I

downward in the form of a resilient memf the shorter member of said element rests on i the bottom of the auxiliary channel 20. The

element 19 is retained by an upturned lip 22 on the bottom wall of the channel 20 at the front of the latter. A resilient controlling element 21 is also housed in the auxil- 'ary channel'QO and is itself approximately U-shape or V-shape in cross section presenting, diverging upper and lower walls, the said walls being forwardly disposed and integral with each other at the back ortoward the inner wall of the groove 0.

The arrangement is such that as the tongue H enters the groove 0 it will engage the oblique resilient member 18 and raise the same, thus raising the returned channel end 20 thereof and carrying the tiltable member 19 and the resilient controlling member 21 'upwardly. In the continued inward movement of the tongue 14, it will engage the rearwardly inclined upper member of the element 19, thus tilting the latter as indicated in Fig. 2, until the said tongue 14 passes over the element 19 and engages the upper wall of the controlling member 21. Thus, an effective contact results between the tongue 11 above and below the same, and the line of contact between the said tongue 14 andthe different surfaces presented by the members 18, 19 and :21 will vary with 5 the shrinkage or expansion of the sash or frame, or with the settling of the building,

so that wind and rain will be excluded under all conditions and the mating tongue and groove members will accommodate themselves to any variation in their relative positions.

The structural embodiment of the invention is'varied according to the position of the tongue and groove elements, whether these be respectively on the sash or frame.

Thus, at the side of the door or window and the janib, the coacting tongue and groove members are arranged. 1n the form shown in Figs. 1. to r, a vertically arranged member 6 10 is applied to the jamb b of the frame B to constitute generally a tongue member, being formed with a tongue 14 as best seen in Fig. 4, while at the adjacent edge of the window G, a niember designated generally 55 as 16 is secured, and may consist, as shown,

At the lower end the resilient" of a plateapplie'd to the vertical edge of the sash at the outer side of a rabbet c therein, The said member 10 is resilient and at'iw free edge is return bent; to produce the tongue 14* which forms with the body-oi the member 10*, a channel'QO' to receive the member 16. In the channel is an angular-1;.

element corresponding With the element 19 and held yieldingly and rockable in the 7 channel 20, there being a lip 22 on the termmal of the tongue 14, A resilient cortrolling element 21 corresponding in gen? eral with the controlling element 21, exerts its pressure on the element 19. Upon the closing of the window G, the tongue 14 will be received in the rabbet c beneath the ole:-

ment 16. The said element will pass over the upper edge of the element 19 between the same and the controlling member 21 to give effective weather-excluding contact be tween the co-acting tongue and groove members. 'The resiliency of the member 10 will permit the tongue 14 thereon to accommodate itself to any. variation in the position of the element 16.

In the form shown in Fig. 5, the invention is embodied in a sliding window involving upper and lower sashes, the co-actmg elegroove 0 is produced in the sash C at the sides and bottom and receives a groove member 16 in. which is an angular yieldin and rockable element 19", corresponding with the elements 19, 19, the same being retained by a lip 22 on the tongue element 16 and by a resilient controlling element 21 corresponding with the elements 21, 21.

The upper sash C has a groove element 16 forming a lining for the groove 0' in the top railand side stiles of the sash, while the mating tongue member designated generally by the numeral 10 is suitably secured to the lintel or top rail of the frame B and the sides thereof and presentsa tongue 14 having a lip 22, a yie din tiltable ele-. ment 19, and a U-shaped resiTient controlling member 21 which is received at the bend thereof in a depression 10 in member-- 10, and bears at the ends of its armson the members of theangular element 19. The meeting rails of the sashes sn'mlarly have the mating tongue and groove members,

there being a groove member 16 in the form of a channel applied to the inner face of the bottom rail of the upper sash, while a tongue member 14 is applied to the op-Q posed face of the top rail of the lower sash, said tongue member having the tiltable. yielding element 19. and'the resilient con tro'iling element 21 integral with the base of the tongue member, said tongue member having the lip 22* correspomling with the lips in the previously described construe tions. The tongue ll" is received in the groove presented by the member 16 while the outer .zlll oi said groove member 14") will engage the element 19 and pass beinent.
